In fantasy novels, there were many places to store spirits. The most common ones were the soul residence or the soul tower. The soul residence usually referred to a specific place where the soul of a character lived after death. This place could be a home, cave, temple, and so on. The Spirit Pagoda referred to a mysterious building that was said to be able to store souls in it to prevent them from being affected by negative factors after death. However, these claims have not been proven by science, so whether they are true or not is still controversial.
